CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 360,360, dated March 29, 1887.

Application filed December S, 1886. Serial No. 221,032. (No model.)

To all whom it may concern..-

Be it known that l, WILLIAM C. MCGILL, a citizen of theUnited States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Cash-Registers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertai ns to make and use the same, reference being had to the accompanying drawings, and t the letters and figures of reference marked thereon, which form a part of this specification.

Myinvention consists in an improved cashu register, which is exceedingly simple in construction and efficient in its operation, and

- which will be hereinafter'fully described and claimed.

Referring to the accompanying drawings, Figure l is a rear elevation of Inyilnproved cash-register, With'a part of the'outer casing broken away. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical sectional view taken on the plane indicated by line 3 3, Fig. 4. Fig. 4 is a vertical sectional view taken on line 4 4, Fig. 2; and Figs. 5 and 6 are detail views, the nature of which will be hereinafter specied. Fig. 7 is a vertical sectional view taken on line 3 3 of Fig. 4, looking toward the front ofthe machine; and Figs. 8 and 9 are detail views, the nature of which will be hereinafter specified.

The same letters of reference indicate corresponding parts in all the figures.

Referringto the'several parts by letter, A, Figs. 2, 3, and 4, indicates the main frame or outer casing, in the lower portion of which fits and slides the money-drawer B, which is slid out into its open position by the spring C,when the locking-plate D is moved to one side, as hereinafter described.

Eindicates the forward upper inclined side ofthe frame A, on the outer face of which are arranged the two sernicircular series of numerals or scales F G, the numerals of the righthand scale running from 0 to 45, representing cents, and increasing 5 at each step, as shown,

. while the numerals of the left-hand scale run from -l to 4l, increasing at each step, as

l senlicircular scales, cach of the said hands being mounted rigidly on the forward outerend of a shaft, I J, the said shafts having their inner endsjournaled in abearing or bracket, K, Fig. 4, near the rear side of the outer casing.

tudinal plate, L, having the downwardlypro jecting side flanges, L, and formed at a suitable distance from each end with the parallel longitudinal series of slots M, nine in each series in the presentinstance. On a transverse rod, N, Fig. 9, extending centrally below and across eachseries of slots, are journaled or pivoted aseries of indicator-plates, O, Fig. 7'- nine on each shaft-the downwardly-projecting stem O' of each plate having its end extended down below the pivot-rod N, and being formed with a curved side arm, O2, extending nearly at right angles to the stern proper, as shown. Each series of plates normally lies over against the right-hand ends of its series of slots in a line at right angles with the front of the Inachine, and in line with a 'fixed plate, l?, at the rea-r edge of the plate L. The first or front plate of the right-hand series is marked with the word Cents or may be left perfectly blank, if preferred. rllhe second plate is marked with the numeral 5, the third with l0, and so on, the last or fixed plate I, which is the tenth plate of the series, being marked with the numerals 45, the numbers on the plates increasing by5, as on the right-hand scale F. The front plate ofthe left-hand series is marked with the word dollars, or may be left blank, if preferred, the Asecond plate being marked with l, the third with 1, and so on, increasing at each step to correspond with the left-hand scale, G, the last or fixed plate, which is the tenth'of the series, being marked with the numerals 4t'.

Around the forward port-ion or end of each shaft, I J, within the outer casing, is coiled a spring, Q, the` inner end of which is affixed to the shaft, so as to move with it, while the outer end is rigidly secured to and near the outer edge of a semicircular plate, It, rigidly mounted on the shaft near its center, and having formed on its broad flanged periphery a series of parallel transverse equidistant ribs or projections, S, Fig. 4, these projections beginning at thc'forward edge of the flange of At the top of the casing A is secured a longi- IOO the plate R, increasing regularly in length from the right, the iirst rib to the right being the shortest, the next twice its length,the third three times aslong, Svc., the eXtremeleft-hand rib being the longest of the series. These ribs project sufficiently to engage with the lower ends of the stems ot the indicator-plates `O when their operating-shaft is turned to the left, as hereinafter described, and a series of projecting radial rods or plates, or other equivalents, may be employed in place of the flanged plate having the projecting ribs, as will be readily understood. To the rear of these anged plates R is loosely mounted on each operatingshaft a drum, T, consisting of the heads connected by the equidistant spokes U, Fig. 4, of which, in the present instance,twenty are used in each drum. The rear head of the right-hand drum is marked with numerals at the ends of the spokes, running from 0 to 45, and again from 0 to 45, as clearly seen in Fig. 1, increasing ve at each step; and the rear head of this drum is formed, at diametrieallyopposite points of its periphery,with the two lugs or projections, V, Fig. l, which are so placed that as soon as the sales registered by this drum amount to fifty cents, and the drum is turned, as hereinafter described, so that the iXed pointer W on the upper edge of the longltndinal supporting frame or bracket K points from 45 to O one of the said lugs will come in contact with .an inwardly-projecting arm, A', formed on the lower vend of a vertical lever, B', pivoted at its upper end to the upper end of a rigid upright arm, C', of the bracket K, thereby pushing forward the said lower end of the vertical lever B', and to this lever is pivoted near its lower end one end of a nearly horizontal lever, D', the free end of which is notched to adapt it to engage with one ofthe spokes of the drum to the left hand, which registers dollars. The rear head of this lefthand drum is marked with numerals at the ends of its twenty spokes, running from 0 to 9%, increasing one-half at each step, as shown. A iixed pointer, W', indicates the amount registered by this drum. The vertical lever B'and horizontal lever D' arethrown back into their normal positions, after the passage of the lugs on the right-hand drum-head, by the spring E', the free endet the said spring pressing againstthe edge of the lever B', as shown in Fig. 1.

D, Figs. l and 4, indicates the locking-plate, which is movably secured against the inner side of the front of the main casi ng by a screw passing through alongitudinal slot, G', formed in it. This locking-plate has a downwardly and rearwardly projecting spring-arin, H', the lower free end ot' which is adapted to engage, when the locking-plate is in its normal position', with a stop or catch, l', on the moneydrawer, and thus hold the drawer in its closed position, and has at each end a spring-pawl, J', adapted to be engaged by lugs K' on the lower ends of the actuating-plates R, the heads of the springpawls being so shaped that the lugs K will lock or engage with them as the plates R are turned to the right, but will slide over them as the plates are returned by the springs Q to their normal position. It will be seen that as either of the index-hands H is turned to the right, carrying with it its operating-shaft andplate R, that the locking-plate will be moved to the left,unlocking the drawer, which is pushed open by its spring C, and as the lug` K' passes the spring-paw] J' the locking-plate is instantly drawn back by a spring, L', to the left, (see Figs. 3 and 8,) when the small clapper M2 at the free end of its auxiliary arm M' strikes against and rings the bell P'.

To the inner side of the rear fiange of the plate L are pivoted near their inner ends the levers Q', Figs. 3 and 7, the inner ends of which are coupled or hinged together, as shown, so that when the outer end of one lever is raised it will raise the outer end of the other; and the levers are formed toward their outer ends with the downwardly-extending lugs R', having the straight right-hand and curved left-hand edges, and at their extreme outer ends with the forwardlyprojecting arms S',.

(see Fig. 9,) which are of sufficient length to extend under all of the side arms, O, of the stems of the indicator-plates O.

To the rear edge of the upper portion of the flange of each actuating-plate R is secured a spring-pawl, T', arranged as shown, the inwardly-projecting head of cach pawl being formed with a straight right-hand and curved left-hand edges.

The righthand plate R has a depending spring pawl or hook, U', which engages with the spokes of and turns the right hand drum to the left as the plate turns to the left, but slides over the spokes as the plate turns to the right. The two drums are prevented from turning backward by the spring-pawls V'. The top of the casingAis closed by a rounded glass top, A2.

The operation oli' my invention is as fot lows: When a sale, say, of five cenls, has been made, the cashier turns the right-hand index-hand H up to the figure 5 on its scale, thereby turning the shaft I and plate R to the right until the first rib, S, comes in contact with and swings the lower end of the stem of the first indicator-plate, O, tothe right, thus throwing the said plate to the left and disclosing to view the numeral 5 on the plate immediately behind it. At the same time this movement of the index-hand unlocks the money-drawer, as previously described, and rings the bell, while the springliook U' slips down' over one spoke of the rightliand drum and engages therewith. The cashier, having dropped the live cents into the drawer and pushed the same in with his other hand, the stop I', raising and passing under the lower end of arm H', releases the handle of the index-hand, when the spring Q throws or turns the index-hand, the shaft, and the plate R to the left to their normal position, the curved edge of the springpawl T' sliding over the straight edge of the lug It' without moving the same, the hook U' turning the cents-registermg drum one space to the left. Vhen the next sale is made, as either index-handv is turned to the right to indicate it, thestraight edge of the pawl T' of that plate R, bearing agalnst the curved edge of the lug R at that end, will raise the said lug, and through it the outer ends of both levers Q', causing the arm S' to bear up against and raise the side arm, O2, of the plate O, which was atthe previous movement thrown to the left, thus throwing that plate back to its normal position and can cehng the indication of the previous sale before moving the indicatorplates to indicate the next sale, in the manner just described, the lefthand plate, R, having a spring-pawl, U2, similar in construction and operation to the pawl U'. As the right-hand drum turns so that the fixed pointer XV passes from to 0 on its rear head, one of the lugs V comes in contact with the arm A', and through the levers B' and D', as previously described, turns the left-hand drum to indicate onchalf dollar. The rear head of this left-hand drum may be iormed with a lug to actuate still further registering mechanism, as will be readily understood. The ribs S are of such length that the first rib will move one indicator-plate, the second two, so as to show the numerals l0 on one side or l on the dollar side, as the ease may be. c When a sale of, say, one dollar and ten cents 1s made, the dollar in dex-hand is first moved so as to disclose the plate of the left-hand series marked 1, and the right-hand index-hand is turned to the numerals l() of its scale. N ow, 1n order to prevent the pawl T' of that plate R from striking the lug It' at that end, and thus throwing the left-hand indicator-plates back so as to hide the -l there disclosed, I employ the pivoted tliumb-lever 7', which can be moved Aby the finger, so that its lower inwardly-curved end will slide behind an outward projection, X', Figs. 3 and 6, at the free end of the spring-pawl T' of the cents mechanism, and will thus hold this pawl back, so that it will not touch the lug It' as the index-hand is moved to indicate the ten cents.

It will be seen that the .one movement of either` index-hand cancels the indication of the prevlous sale, unlocks the money drawer, rings the bell, indicates the amount ofthe new sale, adds the amount last deposited to the previous deposits, andu'egisters the total amount of deposits.

The rear faces of the indicator-plates may be marked with the numbers of the plates j ust behind them, so as to indicate from the rear the numbers shown at the front.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of`my improved cash-register willv be readily understood. f

It will be seen that my improved cash-register is exceedingly simple in construction and efficient in its operation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. In combination with a cash-receptacle, the two series of plates pivoted in a line at right angles with the face of the machine, having each a downward projecting stem and marked with numbers corresponding to the numbers on the registers, the two shafts I and J, having the semicircular plates RR, having attached to their outer edges the ribs corresponding in number to the number of the pivoted plates, and the registering-drums T T, the whole arranged to operate substantial] y as herein set forth.
